In an ideal world all working platforms should contain no gaps or holes. This updated guidance is a simplification of the previous 2003 issue regarding working platforms, which have additional requirements over those that are normally provided on an access scaffold.

This guidance gives details of the stress corrosion cracking (SCC) that can occur in certain materials when subjected to tensile stress and specific corrosive environments. Although rare in our industry, it can lead to unexpected sudden failure of certain metals. Whilst chemical environments and alloys are highly specific, this guidance explains the process by which SCC can occur and advises that specialist advice may be needed where SCC is possible or has occurred in the past.
